Gushichan Chōsei

Gushichan Wōji Chōsei (具志頭 王子 朝盛, 20 May 1578 – 21 August 1610), also known by his Chinese style name Shō Kō (尚 宏), was a Ryukyuan prince who served as sessei, a post often translated as "prime minister", from 1589 to 1610.

Shō Kō was the second son of Shō I (Prince Yonagusuku Chōken) and Shuriōkimi Aji-ganashi. He was also the little brother of King Shō Nei.

Satsuma invaded Ryukyu in the spring of 1609. Shō Kō was taken to Sunpu together with King Shō Nei and a number of high officials by Satsuma troops. He died and was buried there.
